           Summary: WKPrintingView should avoid copying the PDF data
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Printing
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: mrowe at apple.com

In <http://trac.webkit.org/changeset/104377> we switched to copying bytes from a Vector<char> in to an NSData*. It should be possible to use -initWithBytesNoCopy:length:freeWhenDone: to avoid copying. This may require changing some of the assumptions about the state of _printedPagesData as it is likely to require transferring ownership of the buffer to the NSData instance.
